ABSTRACT:
Corrosion of metals in contact with liquid systems is reduced by adding to the system a small amount of a hydrazine salt of an amido carboxylic acid containing at least one hydrophobic group. The hydrazine salt of the amido carboxylic acid is preferably used in combination with an ether amine or a quaternary ammonium compound. The hydrazine salt gives a substantial reduction of both general and localized corrosion and is particularly useful for preventing corrosion in different areas of oil recovery and in petroleum industry.
